Snap-and-seal RCA and BNC Connectors

[kaysadeya 0]

I've looked everywhere and can't find any instructions on how to install snap-and-seal RCA and BNC connectors. All I can find is how to install the F connectors. Can someone point me to the info?

 

Thanks!

I really like SnS. My compression tool doesn't work with the BNC's. Which tool are you using?

3195CT. Have you tried it with the BNC connectors? I just ordered the connectors and assumed they were compatible with this tool:

Guys, what is the snap and seal uses for, outdoors?? If so, why?

I haven't tried with my tool. but the F connectors are a tight fit. I am pretty sure there is no way a BNC will fit in there. I can't tell how that tool you linked to works. I was thinking of picking up something like this:

Yes. SnS make a weather tight connection. But I picked it up at the suggestion of a guy I know that works for the cable company. I figured if it was good enough for them, it was good enough for me. Since then they have switched to Digicon. D'oh!

 

I like the professional look of the compression fittings.

I'll let you know if the connectors fit my tool. What I really need though are instructions (I'm pretty sure the splicing for BNC and RCA s different than with 'F' connectors).

 

Rory, yes the snap-and-seal are designed to create a weather-proof connection. The connectors are just really solid, so I use them everywhere.

I would try it just like the F conns. ?

 

Because unless you have to use a different stripper I don't see how it could be much different.

I haven't yet used the BNC connectors, but I have some RCA connectors (for RG59) that fit the compression tool. However, I've had spotty success with the RCAs, mostly because I really don't understand how far back to cut the cable jacket and how much center pin to expose. From the looks of it, you have to expose a longer center pin with the RCA than you would with an F connector.

 

The RCA connectors aren't cheap, so experimenting is expensive. It would be out of the question to experiment with the BNC connectors, at $5 a pop.

 

I've sent emails to both Thomas & Betts and Sargent. I'll post whatever information I can get from them on this topic.

That's disappointing to hear. I have never had a failure with the F conns. But really, with the exposed center conductor it's pretty easy to know it's all good before you compress the fitting. The closest I can find to instructions for the RCA's was this:

 

For maximun performance use an RG6/U with a solid copper center conductor ie Belden 7915A

 

Quad sealed system prevents moisture from migrating into the connection

360° radial compression provides superior RF integrity.

1/4"x 1/4" cable preparation

Connector to cable retention 40 lbs minimum

Requires the SNSIT for installation

That's what the F conns need. and it's the same instructions they give on the BNC page. But obviously there is more to it then that if you are having failures.

Yes the 1/4" x 1/4" works for the F connector just fine (I did 2 of those today).

 

I also figured out some cuts for the RCA that appear to work: 1/2" x 3/8" (the latter being the exposed center conductor). However, rather than pushing the braid back over the outer jacket (as you do with the F connector), I found that scrunching it up 1/4" back from the exposed center conductor seems to work best.

 

If I don't get any responses from T & B or Sargent next week, I'll have to experiment with the BNC cuts. If I have success on either front, I'll post the results here.

C7. I received the R6 BNC connectors yesterday, but have been distracted by life and my new DVR. The connectors came with instructions (this is new ) and the short story is that the instructions say to cut 1/4 / 1/4. However, looking at the interior of the connector, that doesn't look right. The interior is more like the RCA connector.

 

I'll get back with more specifics when I have them. Meanwhile, I plan to take advantage of this weekend.

Finally got around to installing one of the BNC connectors today. A 1/4 x 1/4 cut is fine; you just have to make sure the BNC connector is twisted far enough up the wire. (I measured the inside of the connector first with a toothpick, transferred the measurement to the wire, and marked.)

 

I also tried the 1/4 x 1/4 splice and same measuring technique with the RCA connector and that worked too. So disregard the 1/2" x 3/8" measurement I cited earlier and just make sure the connector is twisted far enough up the wire before crimping.

why are you using this, is it outside, or just for grins and giggles?

[kaysadeya 0]

Giggles. I get them each time I think about my connectors.

 

I try not to let it happen too much in public, though....
